PLUNGER.

Specification of Letters Batent. Patented lIay 11, 1920.

Application filed November 1, 1919. Serial No. 335,171.

To all whom it may concern:

Be it known that we, STANISLAW Us- TRZYGKI and JOSEPH BUKOLA, citizensof P- land, residing at Chicago, in the county of Cook and State ofIllinois, have invented new and useful Improvements in Plungers, ofwhich the following is a specification.

The object of the invention is to provide a simple and effective meanswhereby obstructions may be removed from drain pipes of sinks, bathtubs, closets and the like, under conditions involving the minimumeffort and loss of time upon the part of the op erator, and to this endthe same consists in a construction and combination of parts of which apreferred embodiment is shown in the accompanying drawings, it beingunderstood that changes in form, proportions and details may be resortedto within the scope of the claims without departing from the principlesinvolved.

In the drawing:

Figure l is a vertical sectional view of the clean out pump applied inthe operative position to a sink outlet, the piston being shown in fulllines in its depressed and in dotted lines in its elevated position.

Fig. 2 is a detail sectional view showing the application of the deviceto a closet,

and embodying anchoring means peculiarly adapted for that purpose.

Fig. 3 is a plan view of the grapple shown in its operative position inengagement with a sink strainer.

The casing embodies a cylinder 11 and is adapted by reason of a foot 12provided with a rubber or other elastic gasket 13 to be seated eitherupon a, sink bottom 14: around the perforated outlet 15 thereof or incontact with the inner surface of a bowl 16 shown in Fig. 2, said gaskethaving both a bottom and a peripheral bearing surface to adapt it forthese several purposes. Mounted in the cylinder 11 is a plunger 17 withwhich is connected a strong spring 18 anchored at its lower end to atransverse bar 19 which in the construction as illustrated consists of ashaft provided at one end, outside of the casing with a hand wheel 20and having associated therewith locking means consisting of the ratchet21 and pawl 22, so that said shaft may be secured in an adjustedposition. Grappling arms 23 may be associated with the device when it isto be used in connection with sink outlets and similar devices forengagement with the openings in the grating or strainer 15, said armsbeing connected with a ring 24 which in turn is attached to the end of achain 25 reeled upon a drum 26 carried by said shaft 19.

In the construction illustrated in Fig. 2, when the device is adaptedfor application to a closet bowl, the grappling arms 27 consist of rodshaving terminal hooks 28 for engagement with the bowl rim 29, turnbuckles 30 being employed to secure the forcible depression of thecasing so as to properly seat the foot 12' upon the inner surface of thebowl.

Also connected with the plunger 17 is a rack 31 extending through aguide opening in the head 32 of the cylinder and engaged by a mutilatedgear 33 adapted for actuation by a worm 3 1 engaging a worm gear 35secured to the mutilated gear or the spindle which carries the same,said worm having its shaft 36 fitted with a hand wheel 37 by which theoperator may communicate motion through the worm and worm gear and themutilated gear to the rack to. elevate the plunger in opposition to thetension of the spring 18. When the elevation of said plunger hasproceeded until the blank portion 38 of the mutilated gear is brought toa position facing the rack, so as to; engage the teeth of the mutilatedgear fromthe rack, the plunger is released to be forced downward by thespring to expel any obstructing accumulation in the pipe incommunication with which the casing has been arranged. Obviously theoperation of the plunger may be repeated by a continuous manipulation ofthe hand wheel 37 until the obstruction has been displaced.

What is claimed is:

1. A clean out pump having a cylinder and a spring advanced plunger, andmeans for securing the same with the cylinder in airtight communicationwith a pipe to be cleaned, a rack connected with the piston and amutilated gear engaged with the rack and adapted upon retraction of thesame to release the piston for actuation by its spring.

2. A clean out pump having a cylinder and means for securing the same inair-tight communication with a pipe to be cleaned, a spring advancedpiston arranged in said cylinder, a rack connected with the piston,mutilated gear in engagement with the rack for retracting and releasingsaid piston and means for actuating the mutilated gear.

3. A clean out pump having a cylinder and means for securing the same inair-tight communication with a pipe to be cleaned, a spring advanced.plunger in the cylinder, a rack connected with the piston, a mutilatedgear in engagement with the rack and adapted to release the same uponretraction of the piston, and means consisting of 10 a Worm andWor-mgear for communicating rotary motion to the mutilated gear.

In testimony whereof We ME); 0111' signa- 'tures.
